HYDRAULIC-POWER MOTOR.

SEPEGIFICATION forming part of Letters Patent No; 534,939, dated February 26, 1895. Application filed April 2,1894. Serial No. 506,006- (No model.)

.To all whom it may concern.-

Be it known that we, JAMES M. ALLEN and ARMAND J. WELOKER, both of the city of St. Louis, in the State'of Missouri, have invented a certain new and useful Improvement in Hydraulic-Power Motors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The object of this invention is to set up increased momentum in a descending column of water by an exhaust produced by a positive power from a suitable motor, and to cause the said momentum to be expended in maintaining a constant pressure in a receiving reservoir to be used in operating a hydraulic motor or in raising a portion of said water to a greater height, as will be described.

Figure I is a side elevation. Fig. II is an end elevation. Fig. III is a section on line IIIIII of Fig. I. Fig. IV is a section on line IV-IV of Fig. I. Fig. V is a top view of the valve diaphragm. Fig. VI is a detail view of the piston 6. Fig. VII is a section view of the piston 6. Fig. VIII is a vertical section of the motor 16. the valves in pipe 11.

Referring to the drawings, 1 is an elevated tank supplied byafiow from a suitable source 3 and 3 are descending pipes connecting at their lower ends with chambers 4 and 4*, each chamber opening into a pump cylinder 5 and 5 in which work pistons 6 and 6*, the piston rods 7 and 7 being provided with lost motion connections by means of collars 8 and sliding block 9, which is connected to the piston rods 9 of a steam engine or other suitable motor, not shown.

The pistons 6 and 6 have ports through them and back check valves 10 and 10 which allows the free passage of water through them on the return stroke of the piston. The forward ends of the pump cylinders are connected to a discharge pipe 11, which leads back to the tank 1. The effective discharge is through the valve diaphragm 12, a plate separating the chambers 4 and 4 from the Fig. IX is a vertical section of l receiving reservoir 13, and provided with a series of check valves 14, which prevent the backward flow into the chambers 4 and 4.

Leading from the reservoir 13 is a pipe 15 which connects with a water motor 16. A discharge pipe 17 is also connected to the chamber 13 for raising water to a greater elevation than the tank 1.

The operation of the machine is as follows: The pistons 6 and 6 on being moved forward by the rod 9 exhaust water from the chambets 4 and 4. At the end of the stroke the valves 10 and 10 in the pistons 6 and 6 rest against the shoulder of the cylinder head and are held closed, thus suddenly stopping the movement of the column of water in the pipes 3 and 3 and the chambers 4 and 4 in this direction. The momentum of these columns of water, induced by their weight .and the action of the pistons 6 and 6 forces parts of the water in the chambers 4 and 4 up through the valve diaphragm 12 into the receiving reservoir 13, which as it is filled up compreses the air at the top. The pistons 6 and 6 are arranged to work alternately, so that there will be a constant flow of water into the chamber 13. This chamber is connected by the pipe 15 to the motor 16, the pipe 15 being of small diameter and terminating in a jet 16 which plays against the motor wheel. The waste water escapes to a chamber 18 which is connected to the pipe 11 and is finally carried back to the tank 1.

When it is desired, the motor may be disconnected and the machine used to elevate water to a greater height than the tank 1,by closing the valve 19, and opening the valve 20 in the pipe 17. When it is only desired to run the motor 16, there need be no in-flow to the tank 1, as the same water may be used repeatedly.

We claim as our invention The combination in a hydraulic power motor of the water-supply, the descending pipes 3 and 6* the chambers 4 and 4, pumping cylinders 5 and 5 located in the chambers 4 and 4, pistons 6 and 6 working in said cylinders and provided with rods 7, 7, piston-rods 9*,

a suitable connection between the rods 7, 7 and 9 collars 8 arranged on the piston-rods 7, 7 to permit the 1031; motion between the motor rods 9 and the said piston rods 7 and 7 a receiving reservoir 13 located above the chambers 4, 4c, the valve diaphragm 12 located between the chambers 4, 4E, and the reservoir 13, and the motor 16 connected with the reservoir 13, and the pipe 11 snbstan tially as shown and described.
